Author: ArthurPeabody (NM) UPC limits slip-joint connections after trap to 1. Does that include the exit connection of the p-trap?

Author: steve (CA) The u-bend of the trap attaches to the trap arm with a non-slip joint connection. The connection of the trap arm to the pipe that comes out of the wall is allowed to be a slip joint.

Author: ArthurPeabody (NM) The exit elbow of a slipjoint trap presents a slipjoint connection. Is that the last one allowed? Or can I have another between that and the inlet for the sanitary tee to which it connects?

I don't think I've ever seen a double slip joint tubular trap. The trap arm either has a flange and gasket, or a ball end that mates with a tapered seat on the trap outlet.

The trap arm completes the "trap", by forming the weir, so I would say a slip joint on the j-bend outlet to trap arm connection is part of the trap and the trap arm connection to the wall tee is the "one approved slip joint fitting permitted to be used on the outlet side of a trap".
